FAQs Of Charcoal Making Machine

What Raw Materials Are Suitable For Making Charcoal?

  1. All kinds of biomass: such as sawdust, rice husk, coconut shell, palm husk, straw, agricultural and forestry waste, etc;
  2. Municipal sludge;
  3. Municipal domestic waste, electronic waste, etc.


  • The purpose of biomass treatment is mainly to make biochar.
  • The purpose of sludge and waste treatment is mainly to achieve waste reduction.

Is It Possible To Process All Kinds Of Raw Materials With One Charcoal Machine At The Same Time?

No, it is not suggested. Because the carbonization time and temperature that are required for the carbonization of biomass, sludge, and various types of garbage are different. And the final product is also different. So, it is recommended to treat different materials during different working hours.

What Are The Requirements For Raw Materials?

  • Standard Technology: size≤20mm; moisture content≤15%; good liquidity;
  • Standard Technology + Dryer: size≤20mm; 15%≤moisture content≤45%; good liquidity;

What Is The Material Carbonization Temperature, Outlet Temperature, Furnace Temperature, And Rotating Speed?

Carbonization temperature of the material: It is also the reaction temperature of the material. Biomass is generally 380 degrees Celsius – 550 degrees Celsius.

Discharge temperature: It is below 30 degrees Celsius (if there is a buffer bin in the list, it does not need to be considered because the whole process is closed and not in contact with oxygen).

Temperature in the furnace: It is about 450 degrees Celsius – 750 degrees Celsius.

Speed: Under normal circumstances, it is 1-9 (The frequency conversion control is based on the actual operation.).

What Is The Reaction Time Of Raw Materials?

Taking wood chips and rice husks as examples, it would take 15 minutes to 25 minutes for the whole carbonization process.

Note: The particle size, density, moisture content of the material, and the phase of the finished carbon would affect the carbonization time. So, the specific carbonization time is up to the condition of your raw materials.

How About Carbon Yield?

Taking wood chips, rice husks, and crushed coconut shells as an example, you can get finished charcoal 280KG—-310KG from 1 ton of the related materials. Commonly, the carbon yield is 3:1. Certainly, the data is based on raw materials with a less than 10% moisture content.

How To Improve Fixed Carbon Content Of Finished Charcoal?

  • Increasing the carbonization time and increasing the temperature in the furnace can improve the fixed carbon content of the finished charcoal. But, it would reduce the carbon ratio.
  • Increasing the rotating speed of the furnace can improve the carbon ratio. But, it would lower the fixed carbon content of the finished charcoal.

So, it is important for you to tell us your requirements for the quality of finished charcoal. Then, we can give a reasonable solution for you.

How About Wood Vinegar And Tar Yield?

For sawdust with 10% moisture and 1t/h feed capacity, you can get appropriately 40-60kg of wood vinegar (PH value 3-4) and 20-40kg of tar. It is an example for you. Tell us the condition of your raw materials, Beston Group(https://bestoncompany.com/) would calculate the wood vinegar and tar yield for you.

What Are Heating Materials For Carbonization Furnance?

Diesel, LPG, natural gas, and recycled biogas from the carbonization process are good available choices as heating materials. For different heating materials, it is better for you to equip the related burners. The preheating time is usually 60-90 minutes.

How About Exhaust Emissions?

Besides charcoal, wood vinegar, and tar, you can get biogas during the whole carbonization process.

First: The combustible gas can be used as heat material for heating the carbonization furnace. In order to reach the energy-saving purpose, we can adjust the usage of combustible gas in the furnace on the basis of the actual situation of gas production. In the best state, you don’t need to purchase other fuels for heating furnace. The recycled combustible gas can satisfy all the heating fuel needs.

Second: With a high temperature of 500-800 degrees burning, it eliminates the harmful components in the mixed gas. So, high-temperature burning reduces the discharging pressure.

How About Temperature Monitoring And Motor?

The complete set of biochar machine has 4-6 thermocouples. That means there are 4-6 temperature detection points. They are located in the main furnace, auxiliary furnace, inlet and outlet of exhaust gas, and outlet of the finished charcoal. They are all connected to the PLC. The temperature data can be got directly from PLC. Meanwhile, fans ‘rotational speed can be adjusted to reach a balance on the basis of each temperature detection data. It is a good way to guarantee the quality of finished charcoal.

Note: The reaction temperature and reaction time of the material will affect the data of the material and the finished carbon.

What Is the Material of Carbonization Main Furnace? What Is The Tolerable Temperature?

It adopts Q245R+310S material that can stand the temperature within 650℃.

How About Service Life?

The system service life of biochar production equipment is 5-8 years. After a lifetime, you just need to change the combustible gas system and pipes. The main reactor can be used after reconditioning.

What Is The Price Of Charcoal Machine?

We are a professional charcoal machine manufacturer and supplier. We would provide the different models and carbonization technology according to your capacity and raw materials. The price of charcoal machine will be different. So, contact us directly to get the accurate price now!

Can Your Machine Meet Environmental Standars?

Yes. The emission can meet the EU emission standard. Certainly, the emission standard is different in different countries. Please send us your local emission standards. Then, we can provide suitable exhaust gas processing technology to meet your needs.

Is It Safe To Run Your Machine?

Yes. The whole carbonization process is under the condition of anaerobic and negative pressure. Therefore, there is no combustible condition for the materials inside the carbonization furnace. What’s more, there is explosion-proof equipment at the end of the equipment. It can guarantee the normal running of the biomass pyrolysis plant.

How About Repair and Maintenance?

Because of different raw materials, different configurations, and different carbonization technologies, we would train the workers to operate the machine after installation. Meanwhile, we would prepare the customized operation and daily precautions booklets according to your project’s actual condition. In the booklets, repairing matters and maintenance matters are concluded. More pictures on Beston Pinterest.
